Six members of a Garden Grove family were hospitalized Tuesday morning after their home caught fire on the 9000 block of Imperial Avenue.

Investigators say two adults suffered burns to their arms, and four children suffered smoke inhalation.

Someone inside the single-story home called for help around 3 a.m. Fire crews arrived on scene a short time later and knocked down the flames in about 20 minutes, according to the Garden Grove Fire Department.

The fire caused an estimated $150,000 in damage. The cause of the blaze was under investigation.
